Dydrogesterone &comma; is also chemically known as 9β&comma;10α-pregna-4&comma;6-diene-3&comma;20-dione&period;Dydrogesterone &lpar;6-dehydro-retroprogesterone&rpar;is a hormonally active&comma; non-androgenic steroid that was developed in the 1950s&period;

Dydrogesterone has selective progestational activity and does not inhibit ovulation&period;&lsqb;3&rbrack; The greater rigidity of dydrogesterone also positively affects its selectivity&comma;while natural progesterone is less selective&comma; existing in different conformations that more easily bind to different receptors&period; As a consequence of its better bioavailability and the progestational activity of its main metabolites &lpar;20-&comma; 21- and 16-hydroxy derivatives&rpar;&comma; the equivalent dose of dydrogesterone is 10-20 times lower than that of oral micronized progesterone&period;

Primary or essential dysmenorrhea is a very common gynaecological phenomenon experienced by women during their reproductive years&period; Clinical studies have shown symptom relief and a reduction in pain with dydrogesterone treatment for dysmenorrhea&period;

Secondary amenorrhoea is not a specific disease&comma; but is instead a symptom&period; Dydrogesterone has been found to adequately induce bleeding within a sufficiently estrogen-primed endometrium&period; When estradiol levels are found to be low&comma; dydrogesterone treatment is more effective when supplemented with estrogens&period;

The objective behind hormone replacement therapy is to actively increase the circulating levels of estrogen to control hot flushes and to prevent the long-term effects of the menopause&comma; such as bone resorption and unfavourable changes in blood lipids&period; The administration of 17β-oestradiol halts&comma; or reverses atrophic changes that occur due to the loss of endogenous oestradiol during the menopause&period;

Estrogen promotes endometrial cell growth and in postmenopausal women with an intact uterus&comma; estrogen monotherapy results in continued endometrial development without the physiological secretory changes normally brought on by progesterone&period; This action is associated with an increased incidence of endometrial hyperplasia and carcinoma&period; Additional protection with progestogens is therefore important in patients with an intact uterus who receive estrogen replacement therapy&period; Dydrogesterone counters the proliferative effect of estrogens on the endometrium and ensures the transition to a secretory pattern and cyclical shedding of the endometrium in serial HRT regimes&period; Dydrogesterone effectively protects against the ontogenesis of endometrial hyperplasia&period; Unlike androgenic progestogens&comma; dydrogesterone does not reverse the benefits brought on by 17β-oestradiol on lipid profiles and carbohydrate metabolism&period; In a continuous&comma; combined HRT regimen&comma; dydrogesterone retards the proliferation of the endometrium so that it remains atrophic or inactive
